House cleaners

B2B buyers must ensure products comply with REACH (EU) or TSCA (USA) regulations. It is critical to request a Material Safety Data Sheet (MSDS) or SDS to verify chemical composition. For eco-friendly lines, look for EPA Safer Choice or EU Ecolabel certifications to validate 'green' claims and ensure the absence of restricted phthalates or volatile organic compounds (VOCs).

Request Active Matter Content specifications; for example, a high-quality multi-purpose cleaner should typically have an active ingredient concentration of 10-15%. Conduct pH level testing to ensure compatibility with surfaces (e.g., pH neutral for marble, acidic for limescale). Always ask for third-party lab reports regarding kill rates for disinfectants (e.g., 99.9% germ kill validation).

For microfiber products, prioritize a GSM (Grams per Square Meter) of 300+ for superior absorption. For mechanical mops, verify the stainless steel grade (SUS 304) of the handle and the rotational durability of the wringing mechanism (tested for >10,000 cycles). Ensure plastic components are made of virgin PP or ABS rather than recycled scraps to prevent brittleness during shipping.

Yes, most professional suppliers on Made-in-China.com offer OEM/ODM services. This includes custom fragrance formulation (e.g., lemon, lavender, or unscented), packaging design (HDPE bottles vs. pouches), and concentrated refill options to reduce shipping costs. Ensure the supplier can provide die-cut templates for label printing that meet regional labeling laws (e.g., CLP regulation in Europe).

Liquids are classified as 'Sensitive Goods' or 'Dangerous Goods' (DG) depending on their flammability and corrosiveness. You must ensure the supplier provides a UN38.3 or DGM report for air freight. For sea freight, use heavy-duty corrugated cartons and palletization with shrink wrap to prevent leakage and handle the weight of high-density liquids.

Utilize Secured Trading Services on Made-in-China.com to ensure payment is only released upon proof of shipment. Conduct a Factory Audit or hire a third-party inspector (like SGS or Intertek) to perform a During Production Check (DUPRO) to verify that the chemical formula matches the approved sample before the bulk order is bottled.

Focus on Tiered Pricing based on volume; for instance, increasing an order from 5,000 to 10,000 units can often yield a 5-8% price reduction. Negotiate for free spare parts (e.g., extra spray trigger heads or mop pads), as these have high failure rates but low production costs for the supplier, providing you with significant added value.

Check for Anti-Dumping Duties on specific materials (like certain plastic components or chemicals) in your country. Ensure the HS Code (typically 3402 for organic surface-active agents) is correctly declared to avoid customs delays. Verify if your country offers tariff preferences for products with a Certificate of Origin (Form E or Form F).
